Touchscreen Controller
• 90% of TSC market is based on resistive technology
• Capacitive has a small share, but is rapidly growing
• Resistive TSC is lower cost than capacitive
• Resistive TSC allows multiple methods of data entry: finger or stylus
• Resistive Well-understood, mature technology
MAXIM today is in the RESISTIVE 4 WIRE
